Embodiment Construction

[0024] The technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only a partial embodiment of the application, rather than the implementation of the whole example. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0025] A kind of shrinking operation method of the battery case is realized by driving two molds (such as upper and lower molds) to move separately, and then adjusting the direction and distance of the two molds accordingly, driving the upper mold and the lower mold to move in opposite directions and press them together For the necking of a battery case, the upper and lower molds have to be separated after each necking is completed, and then it ...

Abstract

The invention discloses a necking assembly and a necking device. The necking assembly comprises a cylindrical base, a driving mechanism and a necking mechanism, wherein the driving mechanism is arranged in the cylindrical base, the necking mechanism is inserted in the cylindrical base through one end of the cylindrical base and is connected with the driving mechanism, a necking part is arranged atone end of the necking mechanism, and a horn mouth shape is defined by the necking part so as to be used for accommodating a battery shell to be subjected to necking; and the driving mechanism is used for driving the necking mechanism to do reciprocating motion relative to the cylindrical base in the axial direction of the cylindrical base so as to enable the necking part to be elastically shrunkor elastically opened. The assembly is simplified and stable in structure, the necking operation process is simple and rapid, a plurality of molds do not need to be adjusted, the phenomenon that necking is conducted before misalignment of the molds so as to cause necking errors and other problems is avoided, so that the necking of the battery shell can be realized quickly, the necking efficiencyof the battery shell is improved, and the yield of batteries is further improved.

Description

technical field [0001] The present application relates to the technical field of battery preparation, in particular to necking components and necking equipment. Background technique [0002] During the production and processing of lithium batteries, one end of the battery case needs to be shrunk, the purpose of which is to eliminate the free movement of the winding core during the movement and shape the case. [0003] At present, the shrinking process of the lithium battery case involves a complicated operation process, which is prone to shrinking errors, and the shrinking operation steps are cumbersome and time-consuming, which easily leads to low shrinking efficiency of the battery case, thereby reducing the productivity of the battery. Contents of the invention [0004] The application provides a necking assembly and a necking device to solve the technical problems that the shrinkage of the battery case is prone to inconsistent sizes and the necking efficiency is not hi...
